WINDOW SASH HOLDER Filed Nov. 2, 1926 ATTO Em.

Patented May 6, 1930 UNITED STATES PATENT EDWARDF. CHAFFEE, OF SYRACUSE, NEW YORK, ASSIGNOB TO THE 0. M. EDWARDS COMPANY INC., Fv SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK WINDOW-SASH HOLDER Application filed November 2, 1926. Serial No. 145,777.

This invention relates-to window construction and has for its object a particularly si1nple and efii'cientmeans by which the sash when in nearly closed position is forced to closed position, particularly sashes having sash starters which tend to stop the lowering of the sash when the sash is nearly but not quite in: closed position.

Theinventionconsistsin the novel features andin the combinations and constructions hereinafter set forth and claimed.

In describingthis invention, reference is had, to, the accompanying drawings in which likecharacters designate corresponding parts inyall the views.

Figure 1' is a fragmentary elevation of a window frame and a sash embodying my invention.

Figure 2 is a detail view-of the rack at each side'of the framegwith which each sash holder coacts.

Figure3-is an innerface view-of thesash holder and starter.

Figure 4 1s an enlarged fragmentary view 5 illustrating the coaction of the bolt of the starter and the lowermost tooth of the rack. Figureb is a fragmentary view illustrating a modified form of the coacting top faces of the plunger and the lever.

This window sash construction comprises a sash holder on the sash having a movable spring pressed member or bolt for engaging a toothed rack along each side of thewindow frame, the'member or bolt and thelowermost tooth of therack having means arranged to act inclined plane fashion on each other when the sash is in nearlybut not quite in its lowermost position so that the force of the spring on said member or bolt tending to thrust the same toward the rack, wedges the sash downwardly into closed position, particularly when the sash is stopped in its downward movement by a sash starter engaging the sill in advanceof the sash, which starter is held in its projected position by the fact that the operator is pinching the handles of the sash lock together.

1 designates the window frame and 2 the sash which may be of anysuitable form, size and construction and of wood sheet metal, cast metal or of any other material and construction.

3is the rack arranged alongeach side of the frame.

a are sash holders mounted at each lower corner of the sash.

Thesash holders here shown are of the con.- struction shown in my Patent No. 1,349,046 dated August 10, 1920, and in my Patent No. 1,567,571 dated December 29, 1925. Each of these sash holders orlatches comprises a casing 5 mountable on the sash and secured thereto in any suitable manner as by screws 6, a member as a bolt 7 slidable in the easing into and out of engagement with the rack 3 and an operating member or actuator 8 pivoted at 9 in the casing and coacting with the bolt member 7 to withdraw it against the action of a spring 10, the lever 8 being arranged in juxtaposition toa pinch handle 11 rigid with the casing 1. As here shown, the spring acts directly upon the bolt.

The bolt is here shown as formed with teeth 12 and 13 and the uppermost tooth 12 which coacts with the lowermost tooth 1 1 of the rack when the sash is closed, is formed beveled at 15 and coacts with a complementally beveled surface 16 on said lowermost tooth. It is not necessary that two beveled surfaces be used, but only that the coacting surfaces be arranged to act inclined plane fashion on each other and in sordoing, force the sash against the sill to its fully closed position. These beveled surfaces are arranged obliquely relatively to the sash in order to also force the sash outwardly and dofvnwardly against the window stop and the The sash holder also includes a sash starter member including a vertically movable plunger 17 guided in the casing and arranged to engage the sill, the plunger being arranged to be depressed by the operating lever 8 when together so that the plungers 17 are projected and engage the sill in advance of the sash so that the sash stops slightly up away from the sill, but owing to the inclined faces 15, 16 of the tooth of each bolt 7 and the lowermost tooth of each rack 3, the sash is wedged to closed position by the springs tending to thrust the bolts 7' upwardly. Hence, the bolts acting inclined plane fashion on the rack when the sash is nearly closed is of particular advantage in a window having a sash starter coacting with the sill.

The plunger 17 is formed with a head 18 having a flat top and the portion or edge 19 of the lever 8 coacting therewith is also fiat, sothat the lever first engages the edge or corner of the head as at 20 nearest the aXis of the lever and the first movement of the lever 8 withdraws the bolt 7 before pressure commences to be applied to the bolt 17 and then only through a great leverage or reduction requiring great movement of the lever. Thereafter the lever engages the opposite corner as at 21 of the head farthest removed from the axis of the lever 8, and more directly applies the power of the handle 8 or applies it through a less leverage or reduc tion and with less movement of the lever. The passage in which the bolt -17 is guided is sufiiciently large to permit the movement of the lever on the head without any appreciable sliding or camming action. Instead of the top of the head 18 and the opposing surface of the lever 8 being flat, either or both may be concave, Figure 5, between the edge portions or corners 20 and 21 or the points where these edge surfaces engage the lever 8.

What I claim is:

1. In a window construction, the combination of a frame, a sash movable in the frame, a rack along the frame and a sash holder. carried by the sash, the sash holder comprising a spring pressed member coacting with the rack and the rack and said spring pressed member having means arranged to act inclined plane fashion and to engage when the sash is in nearly closed position, whereby said'means wedge the sash into fully closed position.

2. In a window construction, the combination of a frame, a sash movable in the frame, a rack along the frame and a sash holder carried by the sash, the sash holder comprising a spring pressed member coacting with the rack and the rack and said spring pressed member having means arranged to act inclined plane fashion when the sashis in nearly closed position, whereby said means Wedge the sash into closed position, said inclined plane means being arranged to force the sash downwardly against the sill and outwardly toward the window stop.

3. In a window construction, the combination of a frame, a sash movable along the frame, the frame being formed with a toothed rack and the lowermost tooth of the rack being formed with a downwardly beveled face, a sash holder mounted on the sash including a spring pressed bolt and a lever for operating it, the bolt having a tooth for coacting with the rack, said tooth coacting with the inclined lower tooth of the rack to force the sash into closed position.

4. In a window construction, the combination of aframe, a sash movable along the frame, the frame being formedwith a toothed rack and the lowermost tooth ofthe'rack being formed with a downwardly beveled face, a sash holder'mounted on the sash including a spring pressed bolt and a handle lever for operating it, the bolt having a tooth for coacting with the rack, said tooth coacting with the inclined lower tooth of the rack to force the sash into closed position and the tooth of the bolt being also beveled complementally to that of the lowermost tooth of the rack.

5. Ina window construction, the combination of a frame, a sash movable in the frame, a rack along the frame, a sash holder carried by the sash, the sash holder comprising a spring pressed member coacting with the rack and an actuator for operating the spring pressed member, the rack and said spring pressed member having means arranged to act inclined plane fashion and to engage when the sash is in nearly closed position, whereby'said means wedge the sash into closed position, a sash starter member associated with the sash holder and projecting in advance of the sash rail to engage the sill and operable to engage the sill in advance of the sash during the movement of the sash holder member by the actuator out of engagement with the rack, whereby during the closing of the sash, the sash starter member holds the sash off the sill and said means acts to fully close the sash when the actuator is released.

6. In a window construction, the combination of a frame, a sash movable along the frame, the frame being formed'with'a rack and the lowermost tooth of the rack being formed with a downwardly beveled face, a sash holder mounted on the sash including a spring pressed bolt anda handlelever for operatingthe bolt, the bolt having a tooth for coacting with the rack, said tooth coacting with the inclined lower tooth of the rack to force the sash into fully closed position,

a sash starter plunger arranged to be acted upon by said lever during the operation thereof to withdraw the bolt, the starter plunger being projected by the handle lever in advance of the sash and hence, projecting in advance of the sash and engaging the sill in advance of the sash when the sash is in nearly closed position and thereby stopping the sash short of closed position and said tooth of the bolt coacting with the lower tooth of the rack to fully close the sash when the handle lever is released.

In testimony whereof, I have hereunto signed my name, at Syracuse, in the county of Onondaga, and in the State of New York, this 29th day of October, 1926.
